7 Claims.

My invention relates to loose leaf folder de'- vices which I propose to form with card board fasteners, in the place of metal binders, in line with present developments which are directed toward the use of other materials than metal in various products.

It is the object ofmy invention to provide for a loose leaf binder arrangement in which a paper board folder is faced on the inside with a paper board backing and binder element which embodies tongues to pass through slots in the sheets of paper to be bound, the structure being provided with passageways for the tongues whereby they traverse the back of the binder, either beneath the binder element or out around the back of the folder itself, returning through passageways into the opposite side from that in which they were introduced, the tongue ends remaining inside of the paper board folder. By providing for a number of fold lines in the tongues they will stay in place. By providing that the tongues be formed on a backing piece enclosed within the folder, I obtain strength in the construction where it is needed, and grip the papersheets at their edges within the slotted portions for the tongues.

' I have illustrated several modes of carrying out my invention and others will no doubt occur to those skilled in the art, the invention inherent in the illustrated and described examples being set forthin the appended claims.

In the drawing:

Figure 1 is a perspective of one form of the structure opened and showing the inside of the foldenf Fig. 2 is a section on the line 22 of Fig. 1 on a larger scale.

Fig. '3 is a perspective of the arrangement of Fig. 1 showing a detail which illustrates the mode of holding a pack of paper sheetsin the folder.

Fig. 4 is a section on the line 4-4 of Fig. 3.

Fig. 5 is a detail of the backing member showing a different arrangement of tongues from that of Figs. 1 to 4.

Fig. 6 is a perspective of an open folder showing a difierent way of mounting. the backing member, in this instance the tongue slots or passages being to the outside of the back of the folder and returning into the folder again.

Fig. 7 is a view on the line 1-1 of Fig. 6 on a larger scale.

Fig. 8 is a section through the modification of Fig. 6, corresponding to Fig. 4, for the first modification.

The illustrated forms of the invention show in each instance a folder having side leaves I, 2 and a back 4. Also in the folder of Fig. 1 are slots 3' at one edge of the side 2, whereby sheets of paper may be marked to fit the tongues of the binder and inner backing element. In Fig. 6 there are two sets of slots 3 and the folder is scored at 30,- this being also for the purpose of slotting the paper.

The binder and backing element is a channel shaped piece of paper board having a back 5 and sides 6 and 1. Tongues 8, either arranged along but one of the sides 6 or 1 (Fig. 5), or alternately extending from the sides 6 and- 1 are provided, said tongues preferably scored at four places, as at to make up four bendable sections therefor.

In the form shown in Fig. 1, the binder and backing element is stapled by means of staples 9 in pairs, to the back of the folder member.

These staples are arranged with the pairs spaced so as to coincide approximately with the distance between the tongued portions of the binder member. Thus there are passages left underneath. the base of the binder or backing memher, through whichthe tongues can be thrust.

In the modification of'Fig. 6, the binder memher is cemented to the back of the folder and in this instance slots to and H are formed in the back of the folder itself tongues out from the inside of the folder and back again.

As so constructed in any of the forms, paper is placed between the sides of the binder memher, the tongues are thrust through the paper, thence bent down on a' score line, thence bent on another score line to pass between the binder and the back of the folder, or else outside the folder as in Fig. 8, and thence bent on the final score line so as to lie against the side of the binder from which they came. If the tongues are on alternate sides or the same side, there is no difference in the manipulation except direction. Where the binder is cemented down, the tongues pass through slots, as noted, across the back of the folder and back in through the far side of the back again ending at the side of the binder from which they came. Thus an approximately complete loop is formed by means of the tongues within which loop the paper is held. With care in handling the tongues the binder will last for a long tim The paper board may well be moisture proofed, so as not to break down upon accidental wetting.

No metal is used except the staples in the one form and even these structure of Fig. 6. It is more desirable to use for passage of the may be omitted, as in the the staples, and have the tongue passages between the back of the binder element and the back of the folder. Local cementing might erve this purpose, leaving uncementedportions for tongue passage, but this would not be as strong in the end as the structure using the external path of the tongues, in my opinion.

Having thus described my invention, what I claim as new and desire to secure by Letters Patent is:

l. A loose leaf paper binder comprising a folder member, and a binder element of fibrous material, said binder element secured to the folder member, tongues extending from the binder element, each of a length to form a loop Passing through the paper, around the binder element and returning alongside of the portion of the binder element where the tongues started, the aforesaid folder member and binder element being arranged to provide passages for said tongues between said binder element and said folder member, said tongues being of flexible construction and retainable in paper holding position frictionally between said folder member and said binder element.

2. A loose leaf paper binder comprising a folder member, and a binder element, said binder element secured to the folder member at the back thereof, tongues extending from the binder element, each of a length to form a loop passing through the paper, around the back of the binder element and returning alongside of the portion of the binder element where the tongues started, the aforesaid folder member and binder element being arranged to provide passages for said tongues through said path, said binder element having sides and a back portion to grip the paper beyond the portion thereof that receives the tongues. I

3. A loose leaf paper binder comprising a folder member, and a binder element, said binder element secured to the folder member at the back thereof, tongues extending from the binder element, each of a length to form a loop passing through the paper, around the back of the binder element and returning alongside of theportion of the binder element where the tongues started, the aforesaid folder member and binder element being arrangedto provide passages for said tongues through said path, said binder element being secured at interspaced points to the back of the folder member on the inside thereof. said securing being such as to leave passages between the back of the binder element and the back of the folder member for the tongues to traverse.

4. A loose leaf paper binder comprising a folder member, and a binder element, said binder element secured to the folder member at the back thereof, tongues extending from the binder element, each of a length to forma loop passing through the paper, around the back of the binder element and returning alongside of the portion of the binder element where the tongues started, the aforesaid folder member and binder element being arranged to provide passages for said tongues through said path, the folder member having slots alongside the back portion thereof through which the tongues will pass in passing around the back of the binder element.

5. A loose leaf paper binder comprising a folder member, and a binder element, said binder element secured to the folder member at the back thereof, tongues extending from the binder element, each of a length to form a loop passing through the paper, around the back of the binder element and returning alongside of the portion of the binder element Where the tongues started, the aforesaid folder member and binder element being arranged to provide, passages for said tongues through said path, said binder element having sides and a back portion to grip the paper beyond the portion thereof that receives the tongues, the tongues projecting from at least one side, and the back portion being secured to the' back of the folder member on the inside by spaced staples, thus leaving between them the passages aforesaid.

6. A loose leaf paper binder comprising a folder member, and a binder element, said binder element secured to the folder member at the back thereof, tongues extending from the binder ele ment, each of a length to form a loop passing through the paper, aroundthe back of the binder element and returning alongside of the portion of the binder element where the tongues started, the aforesaid folder member and binder element being arranged to provide passages for said tongues through said path, said binder element having sides and a back portion to grip the paper beyond the portion thereof that receives the tongues, the tongues projecting from at least one side and the back portion being secured to the back of the folder member on the inside by cementing, said folder member back having slots at each Side edge thereof,to provide the said passages for the tongues.

7. A loose leaf binder comprising a folder member and a binder element of fibrous sheet material, said binder element having a body secured to the folder member and tongues extending from said body, said tongues each being of a length to form a loop passing through perforations in paper to be bound in said binder and around the binder element, said loop when said tongues are so positioned being of double thickness in sub stantial part, the said tongues being transversely scored at intervals whereby to cause them to conform to'the paper and binder element when they are in loopformation, the aforesaid folder member and binder element being arranged to provide passages for said tongues in said loops.
